Mac Mini purchase advice

My Macbook is showing its age (memory maxed , hard drive tapped, hardly no battery life when not connected to an outlet). I’m thinking about the Mac Mini as a replacement. It’s cost efficient and I should be able to connect it to my LED using HDMI (hello, big screen).

My personal use cases are
-internet browsing
-occassional video watching
-lots of music listening
-game (though i haven’t been able to play a Mac game in years because of hardware/space restrictions)

My question is: would the $799 mini make me happy or should I hold until the next refresh?
